隨著全球對於可再生能源需求的日益增加，太陽能史特林引擎(Solar energy Stirling Engine)因其較高能源轉換效率而受到廣泛關注，同時氫能源也是一種乾淨的燃料。本研究提出一種太陽能史特林引擎水冷及產氫技術。利用史特林引擎的廢熱加熱甲醇水溶液以及觸媒重組器，進行甲醇水氣重組(Steam Methanol Reforming, SMR)反應產出氫氣，同時提高引擎的效率。
相較於空氣冷卻，水冷預期可有效增加史特林引擎的冷熱端溫差，並且利用引擎散熱端的廢熱將甲醇水溶液蒸發進行重組反應產生氫氣。本研究通過建立實驗裝置，驗證此概念的可行性。此外，根據實際觀測數據，相較於空氣冷卻，水冷太陽能史特林引擎的效率可有效提高。同時，本研究也設計了雙層重組器，相較於單層重組器，可顯著提升產氫效率。

As global demand for renewable energy continues to increase, solar energy Stirling engines have garnered widespread attention due to their relatively high energy conversion efficiency, while hydrogen energy is also recognized as a clean fuel. This study proposes a solar energy Stirling engine combined with water cooling and hydrogen production technology. The waste heat from the Stirling engine is used to heat a methanol-water solution and a catalytic reformer, facilitating the Steam Methanol Reforming (SMR) reaction to produce hydrogen while simultaneously improving the engine's efficiency. Compared to air cooling, water cooling is expected to effectively increase the temperature difference between the hot and cold ends of the Stirling engine. Additionally, the waste heat from the engine's cooling end is utilized to evaporate the methanol-water solution, driving the reforming reaction to produce hydrogen. This study establishes an experimental setup to verify the feasibility of this concept. Furthermore, based on actual observational data, the efficiency of the water-cooled solar energy Stirling engine is significantly improved compared to air cooling. Additionally, a dual-layer reformer was designed in this study, which significantly enhances hydrogen production efficiency compared to a single-layer reformer.
